Description
Technical field
The utility model relates to visual illumination light source, particularly relates to the lighting source of wheel mould character identification system.
Background technology
Machine vision is automatically obtained by optics, non-contacting camera and the imaging of an interpretation process real-world object, so that obtains information needed or the process for control machine and detection.In nearly 30 years, obtain swift and violent development, its application is throughout industry, agricultural and military etc.By computer technology to the intersection of Dynamic Non-Destruction Measurement and infiltration, machine vision one of having become in Dynamic Non-Destruction Measurement has much the branch of vitality, and opens the brand-new application of Dynamic Non-Destruction Measurement.The product quality that machine vision is usually used in large batch of production process detects, especially dangerous at testing environment and the implacable occasion of human eye vision.
Wheel mould is the mould manufacturing tire, and the word on wheel mould is all minute surface word, and because people is to the thinking set of word, the detection of minute surface word to the eyes by people causes sizable difficulty.Error rate is higher, and the efficiency detected is lower.In addition, once occur undetected, great economic loss can be caused.
Lighting source on the market for reflective severity is generally bowl-type, and the field of illumination of bowl-type diffuse reflection light source is circular, and the region of taking turns the word on mould is the annular across whole visual field, the loss of many light quantities can be caused like this, reduce the utilization rate of light quantity, and the brightness at often edge is lower, the uniformity is not enough.
Summary of the invention
The utility model object is to overcome above-mentioned existing technical deficiency, proposes that a kind of profile radian is variable, light quantity utilization rate is higher, the diffuse reflection light source of the wheel mould character identification system of Uniform Illumination.
To achieve these goals, the utility model provides following technical scheme:
The lighting source of wheel mould character identification system, comprise main support, wherein the center of main support is circular hole, and this circular hole is the through hole of video camera, and be connected with time support in the both sides of main support, two ends of this support are provided with shell; Main support, secondary support and shell form integral support, and be bonded with resilient materials in this integral support surface coverage, such as rubber, be fixed with LED module in the bottom of shell, this shell is connected with hinge, is connected with screw rod between hinge.
One as the technical program is improved, and the outer surface of described resilient materials scribbles silver color and sprays paint, and inner surface scribbles white diffuse reflecting layer, thus is conducive to the utilization ratio and the irradiation uniformity that improve light quantity.
Another kind as the technical program improves, and this inner surface of outer cover scribbles diffuse reflector.
As another improvement of the technical program, LED module comprises LED array, and this LED array becomes certain angle of inclination with shell, is preferably 15-45 degree angle, thus makes the Illumination Distribution of light source inner top surface more even.
As the further improvement of the technical program, described LED module bottom surface has louvre, to reduce the loss of LED, extends the service life of LED.
Further, rivet interlacement is passed through between described main support and secondary support, shell.
Further, described hinge is connected by nut and pad with screw rod, by rotating nut, to adjust the angle of two shells.
In a word, the utility model compared with prior art, has following beneficial effect:
The utility model lighting source is the lighting source of wheel mould character identification system, because wheel mould surface reflection is severe, so this lighting source belongs to diffuse reflection light source, eliminates the impact that the speck that formed because of mirror-reflection causes picture quality.Because light source profile and wheel mould character area are all annulars, make its light quantity utilization rate higher, irradiation uniformity is better.In addition, because the diameter of taking turns mould varies, can rotating nut be passed through, change the angle of two shells, because the effect of resilient materials, time support is rotated, cause the radian of whole light source profile to change, make it want to coordinate with the diameter of wheel mould, make the practicality of this lighting source stronger, thus solving existing bowl-type diffuse reflection light source, light quantity utilization rate is low, the technical matters of irradiation uniformity deficiency.

Detailed description of the invention
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
Below in conjunction with the Figure of description in the utility model, be clearly and completely described the technical scheme in utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, for the lighting light source structure schematic diagram of the wheel mould character identification system of the utility model preferred embodiment, comprise main support 2, wherein the center of main support 2 is circular hole, this circular hole is the through hole of video camera, be connected with time support 3 in the both sides of main support 2, two ends of this support 3 are provided with shell 6; Main support 2, secondary support 3 and shell 6 are connected to form integral support by rivet 4, and cover at this integral support inner surface and be bonded with resilient materials 1, wherein, the outer surface of resilient materials 1 scribbles silver color and sprays paint, and inner surface scribbles white diffuse reflecting layer.
Wherein, the inner surface of shell 6 scribbles diffuse reflector, is fixed with LED module in the bottom of shell 6, this LED module comprises LED array 10, LED array 10 inclination angle certain for 6 one-tenth, shell, is preferably 30 degree, this shell 6 is connected with hinge 8, is connected with screw rod 5 between hinge 8 and hinge 8.
Wherein, hinge 8 is connected by nut 7 and pad 9 with screw rod 5; Hinge 5 both sides have nut 7 to be connected with screw rod 5.
The utility model lighting source is a diffuse reflection light source, and this light source is for die surface smoother, reflective more severe situation.Because die surface smoother, a part of light generation mirror-reflection, so die surface can present the fuzzy inverted image of light source, obtain Uniform Illumination effect and avoid the impact of speck, just requiring the uniform-illumination that light source inner top surface receives.As long as irradiate the uniform-illumination of inner top surface, after light generation diffuse reflection, be uniform in the distribution in space, i.e. brightness uniformity.So the fuzzy inverted image of light source that die surface presents also is brightness uniformity.So just realize the Uniform Illumination in the region that need detect and avoid the appearance of speck.The light of light source inner top surface is mainly from two parts, and a part is the direct irradiation of LED array 10, and another part is the reflection through light source medial surface.The latter is that edge illumination is higher at the illumination calibration of inner top surface.So will, by changing the inclination angle of LED array, allow its light lean on toward center, thus inner top surface uniform-illumination after realizing the superposition of two parts light.As shown in Figure 3, for the Illumination Distribution figure of light source inner top surface, Fig. 4 are the distribution curve of illumination of straight line x=30, in curve, minimal illumination is 7520lux, maximal illumination is 8500lux, and inner top surface minimal illumination is 7300lux, and the uniformity reaches 86%(minimal illumination divided by maximal illumination).
